请求地址:http://japi.juhe.cn/voice_words/getWords

此接口必须用POST请求，java网络请求有HttpClient相关工具包及HttpURLConnection相关的包等，这里用的是HttpClient，需要先导包，如果用maven话会更方便直接把下面的复制到pom.xml:org.apache.httpcomponentshttpmime4.3.6org.apache.httpcomponentshttpclient4.4.1

请求代码如下:package com.jefferson.utils.interfaceDemo.voice_words;
